Question

Solve using quadratic formula. x^2-8x+15=0 I don't know what I'm doing wrong :(

Answer 1

What answer did you get?

Answer 2

something with a sqaure root sign when i should be getting actual numbers

Answer 3

you should be getting x = 5,3
I actually factored it without using the quadratic equation but if I did use the quad. eq. I would get the same answer:
8 plus or minus the square root of 64-60 divided by 2

Answer 4

Positive 64? that's probaby where i've been messing up

Answer 5
